Version 1 and 2 are a bit older, not really special. I got version 3 and 4.
So… version 3 is “vacuum suction” ? Didn’t feel much but.. well. Version 4 feels kinda better.
G-Project does the best “penis hats” I say, the material feels good, is more firm than Tenga’s and doesn’t look “cheap” like Toysheart’s. There is a little.. suction chamber. Press the air out and it gives… suction yeah exactly 😀
What else can I say, pretty everything has already been said about this kind of onaholes… Easy to carry, easy to use, easy to wash, doesn’t cost much. A convenient masturbation tool who feels better than the raw hand and prevents spilling the semen all over the place. Easy to store and doesn’t obviously look like what it actually is, therefor a good idea for who lives with his family.
